Redflow Limited announced that its safe, scalable, and sustainable flow batteries have been funded and approved by the California Energy Commission (CEC) for a large-scale solar and storage project, which will provide power for the Paskenta Band of Nomlaki Indians. The 20 MWh system will be one of the largest zinc-based battery projects in the world. With this new 20 MWh project, Redflow joins a small number of commercially proven non-lithium storage providers that the CEC is funding, as it looks to compile a robust portfolio of long-duration energy storage projects.

The projects represent a key step to help address an estimated 45-55 GW of long-duration energy storage required in California by 2045 to support grid reliability and the state's clean energy transition targets. The project will be funded by the CEC's USD 140 million long-duration energy storage grant program focused on enabling commercially proven non-lithium energy storage technologies to scale. This follows the 2 MWh system in California that Redflow installed for Anaergia in 2022 that has been successfully operating for more than a year.

CEC-funded long-duration energy storage projects have often been deployed to benefit underserved communities while helping the state address grid stability and resiliency in extreme weather conditions. This solar and storage microgrid will enable the Paskenta Tribe to power operations of the Paskenta Rancheria using a sustainable, resilient renewable energy solution. The project is part of the Tribe's efforts to achieve greater energy sovereignty through control over their own energy resources, reduce fossil fuel consumption, and assert responsible land stewardship.
